The Indigofera obcordata flowers in picture bear their banner petals below or to the left. The visible outside surface part of one banner or standard shows the fine hairy covering expected there. On the inside the red to brick red banners have dark, parallel veins to the upper margins.
Similar veins are present on the wing petals. The paired wings stand tall here, widening away from the flower centre. They obscure the shorter keels between them.
The obcordate (or obovate) leaves are not as hairy as sometimes seen, but fold in along their midribs as is normal. Some of the thickish leaf margins are dull maroon (Vlok and Schutte-Vlok, 2015; iNaturalist).
